tons, and the field appears to be in good condition for a 

 fine product next year. Here we have what may be 

 considered a fair experiment, which proves that without 

 the use of animal excrement, a worn-out field may be 

 brought to produce very generous crops — crops wliich 

 pay a good return for the expense incurred. It proves 

 that chemical unorganized agents are capable not only of 

 supplying nutriment to plants for a single year, but for 

 sustaining crops for a series of years. The fertilizing 

 elements supplied for the five years cost a little less than 

 thirty dollars. The experiment upon this field is not re- 

 garded as finished, and the crops will be noted until they 

 are observed to falter.
